Perhaps you have heard of “salsa verde,” or green salsa. The word “verdant” is related to the word for green in Latin as well as Spanish ("verde") and French ("vert"). It means green with plant growth, usually describing the countryside. In some translations of the Bible, one finds the expression, “in verdant pastures,” describing the location of the shepherd’s work. This means in green, lively pastures. Thus, among the options provided, “lush” is the best, as it means growing to a great degree.

The word “indigenous” means “native to a given location” or at least coming from that place. For instance, one can speak of the “indigenous people” living in Australia as opposed to the British settlers who later arrived there. Do not confuse the word “indigenous” with “indigent,” which means “poor” or “needy.”

“Bleak” means desolate, bare, lifeless, and depressing. A situation can also be “bleak,” which means hopeless. As for the other answer choices, “fertile" can mean able to produce lots of vegetation and crops; "abundant" means found in large numbers; “perceptive” means insightful, sensitive, and noticing many things; and "flagrant" means overt and brazen and is often used to describe instances in which someone purposely breaks rules.

"Agrarian" is an adjective that means pertaining to the countryside or farmers. The best choice is "rustic" because it shares the meaning of pertaining to the countryside. Considering the other choices, "angry" is not appropriate because it means expressing anger, "trite" means meaningless due to overuse. "Growing" and "natural" may each seem like good answer choices because they have connotations related to farms and farming, but "rustic" is the answer choice closest in meaning to "agrarian," so it is the correct answer.

Whenever someone is "languishing," he or she does not have energy. The adjective "languid" describes a person who is at least acting like he or she does not have much energy. Sometimes it has the connotation of being lazy, though it can merely mean that a person is being sluggish or slow in his or her actions.

A person who is "impassioned" can also be described by the simpler adjective "passionate." Such a person displays great energy in his or her devotion to a given topic or activity. "Fervor" is an intense emotional state. When someone is described as being "fervid," he or she is passionate.

When someone is described as being "conscientious," this means that he or she has a desire to follow his or her own conscience when executing his or her duties and obligations. Such a person desires to do things correctly and ably—as opposed to someone who merely wishes to do "well enough" without worrying about doing a good job. We would also describe such a conscientious person as being "diligent."

"Dour" is an adjective that refers to someone's manner or appearance and has a few different meanings, including gloomy and austere. While "dilapidated" sounds like it might be a good answer choice, it means in poor condition due to having been neglected over time—not quite what we're looking for. "Grim," on the other hand, can mean somber or gloomy and is the closest in meaning to "dour," so it is the best answer choice.

The word “prudent” has perhaps received a bad sense in its standard usage by most English-speakers. One will at times speak of “prudent” people who know how to work things to their gain. For instance, someone might be called “prudent” for keeping silent about opinions instead of insulting someone who might give him or her a job; however, the word “prudent” is of much nobler origins, meaning discerning or even wise in practical action. For this reason, among the options provided, the best option is “judicious,” meaning judging well. This meaning will cover the more negative uses but likewise applies to the nobler notions of “prudence.”
